Settings titles should appear in top area, not content area

[holmesworcester]

Right now settings titles that (like "Notifications" here) are in the content area. They should be in the top bar.

(To reproduce, click the community name in the top left to open settings, then navigate through all the different settings sections.)

Hi! I'm new to open source and would love to work on this issue. Could you please assign it to me?

Sure! Also this might require some refactoring and not be as simple as it seems so feel free to let us know if you'd prefer another issue!
